Osteoporotic fractures are common among older people, and hip fractures (HF) can be devastating. Surgery is indicated for most cases of HF, and chronic persistent postoperative pain is likely to occur. This study investigated the multifaceted factors related to persistent pain occurring during the acute phase and subacute phase of recovery after HF surgery. We conducted a prospective 8-week study of older HF patients after surgery. We evaluated pain intensity, depression symptoms, the fear of falling, pain catastrophizing, cognition and attention, the ability to perform activities of daily living, and the physical performance at 2 weeks (acute phase) and at 4 weeks (subacute phase) after surgery. Patients were divided into the light group (Verbal Rating Scale (VRS) score ≤1) and severe group (VRS score ≥2) according to pain intensity at 8 weeks (recovery phase) after surgery. Factors affecting persistent postoperative pain during recovery were examined using logistic regression analysis. Seventy-two patients were analyzed: 50 in the light group and 22 in the severe group. In the severe group, pain with movement and Pain Catastrophizing Scale scores were higher than those of the light group at 2 weeks and at 4 weeks after surgery. The regression analysis showed that pain with movement at 2 weeks and at 4 weeks after surgery and pain catastrophizing at 4 weeks after surgery were related to persistent postoperative pain. HF patients may have persistent pain if they continue to experience pain and catastrophize their pain during the acute phase and subacute phase after surgery.

髋部骨折患者持续性术后疼痛的影响因素

骨质疏松性骨折在老年人中很常见，而髋部骨折（HF）可能具有破坏性。大多数HF患者都需要手术治疗，并且可能会发生慢性持续性术后疼痛。这项研究调查了与HF手术后恢复的急性期和亚急性期持续疼痛有关的多方面因素。我们对老年HF患者术后进行了为期8周的前瞻性研究。我们评估了术后2周（急性期）和4周（亚急性期）的疼痛强度，抑郁症状，对跌倒的恐惧，疼痛的灾难性，认知和注意力，进行日常生活活动的能力以及身体活动的能力。根据术后8周（恢复期）的疼痛强度将患者分为轻度组（言语评分量表（VRS）评分≤1）和重度组（VRS评分≥2）。使用逻辑回归分析检查了影响恢复期间持续的术后疼痛的因素。分析了72例患者：轻度组50例，重度组22例。在重度组中，术后2周和4周时，运动疼痛和疼痛灾难性评分得分高于轻度组。回归分析显示，术后2周和4周运动时疼痛和术后4周灾难性疼痛与持续的术后疼痛有关。
